Nächstkommender Stand der Technik ist ein Verbindungselement (US-A-5,641,255), bei welchem der äußere Umfang des Oberteils in Form einer glatten Außenwandung ausgebildet ist. Hierdurch ist es einerseits einfach, Trägeröffnungen zu durchsetzen, wobei jedoch andererseits die Haltewirkung in axialer Richtung nur von der Spreizwirkung des Unterteils abhängt. Damit ist keine sichere Befestigung innerhalb zweier Öffnungen von Trägern gegeben.The closest prior art is a connecting element (US-A-5,641,255), in which the outer circumference of the upper part in the form of a smooth Outside wall is formed. On the one hand, this makes it easy to make carrier openings to enforce, but on the other hand, the holding effect in the axial Direction only depends on the expansion effect of the lower part. There is no such thing given secure attachment within two openings of beams.

Weiterer Stand der Technik ist eine Verbindung zwischen einem Träger, insbesondere einem Karosserieteil eines Kraftfahrzeuges und einem Plattenelement (DE 197 53 678.6). Darüber hinaus ist ein einstückig ausgebildeter Kunststoffklipp bekannt, welcher durch Eindrücken eines oberen Bereichs in einen unteren Bereich über Eingriffselemente eine Verbindung herstellt und damit seine Schließfunktion erfüllt (EP 0 415 509 A1).Another prior art is a connection between a carrier, in particular a body part of a motor vehicle and a plate element (DE 197 53 678.6).

This external toothing 20 can for example be made in the manner of a so-called "fir tree bolt"; it exists however, also the possibility, not shown, of the external toothing 20 to make it spiral or in some other form.

Der Schaft 16 weist insbesondere nach Fig. 2 eine durchgehende Ausnehmung 32 auf, welche gemäß der rechten Darstellung von Fig. 2 konische Sektoren 38 besitzt. Diese konischen Sektoren 38 münden in einen unteren verengten, eine Gegenrast 12 bildenden Bereich (Fig. 1). Stirnseitig ist die Ausnehmung 32 mit einer Einführschräge 35 versehen.The shaft 16 has, in particular according to FIG. 2, a continuous recess 32, which according to the right representation of FIG. 2 conical sectors 38 has. These conical sectors 38 open into a lower narrowed one Counter detent 12 forming area (Fig. 1). The recess 32 is on the end face an insertion bevel 35 provided.

Alternativ besteht nach Fig. 2 linke Darstellung auch die Möglichkeit, dass der Schaft 16 innenseitig der durchgehenden Ausnehmung 32 mit Längsrippen 40 versehen ist, wobei wiederum deren unterer verengter Bereich die Gegenrast 12 bildet. Endseitig besitzt der Schaft 16 eine Zentrierschräge 19.Alternatively, there is also the possibility according to FIG. 2 on the left that the Shaft 16 on the inside of the continuous recess 32 with longitudinal ribs 40 is provided, the lower narrow region of which is in turn the counter-latch 12 forms. At the end, the shaft 16 has a centering slope 19.

Das erfindungsgemäße Verbindungselement weist neben dem Oberteil 1 ein Unterteil 2 gemäß Fig. 3 und 4 auf. Dieses Unterteil 2 besteht aus einem oberen Abschlussflansch 22 und einem Zylinderbereich 18 mit einem Rastbereich 15. Der Abschlussflansch 22 weist oberseitig mindestens eine Eingriffsausnehmung 26 für ein nicht näher dargestelltes Demontagewerkzeug auf. Unterseitig ist der Abschlussflansch 22 mit mindestens einer Gegenverzahnung 21, beispielsweise in Form von diagonal gegenüberliegenden Zähnen, versehen. Die Gestaltung und die Anordnung dieser Gegenverzahnung 21 des Unterteils 2 ist auf die zentrische Innenverzahnung 21 des Oberteils 1 abgestellt. The connecting element according to the invention has in addition to the upper part 1 Lower part 2 according to FIGS. 3 and 4. This lower part 2 consists of an upper one End flange 22 and a cylinder region 18 with a latching region 15. The end flange 22 has at least one engagement recess on the upper side 26 for a dismantling tool, not shown. The underside is the End flange 22 with at least one counter toothing 21, for example in the form of diagonally opposite teeth. The design and the arrangement of this counter toothing 21 of the lower part 2 is on the central Internal teeth 21 of the upper part 1 turned off.

Der Rastbereich 15 des Unterteils 1 besitzt in Umfangsrichtung zwischen zylindrischen Sektoren 28 mehrere Rastausnehmungen 24. Vorzugsweise sind jeweils vier zylindrische Sektoren 28 und vier Rastausnehmungen 24 vorgesehen.The locking area 15 of the lower part 1 has in the circumferential direction between cylindrical Sectors 28 have a plurality of notches 24. Preferably each four cylindrical sectors 28 and four locking recesses 24 are provided.

An den Rastbereich 15 des Unterteils 1 schließt ein Übergangskegel 30 und ein im Querschnitt kreuzförmiges Profil 33 an, welches in ein konisches Ende 36 übergeht. Der obere Durchmesser dieses konischen Endes 36 entspricht in etwa dem Durchmesser des zylindrischen Bereiches 18 des Unterteils 2.At the locking area 15 of the lower part 1 includes a transition cone 30 and in cross-section profile 33, which in a conical end 36 transforms. The upper diameter of this conical end 36 corresponds approximately the diameter of the cylindrical region 18 of the lower part 2.

Zur Vormontage wird das Unterteil 2 gemäß Fig. 5 so in das Oberteil 1 eingesteckt, dass sich der vordere Bereich des Übergangskegels 30 des Unterteils 2 auf der Oberseite der Gegenrast 12 des Oberteils 1 befindet. In dieser Position ragt der Flansch 22 des Unterteils 2 um einen gewissen Betrag über den Flansch 10 des Oberteils 1 heraus. Das konische Ende 36 des Unterteils 2 und die Zentrierschräge 19 des Schafts 16 des Oberteils 1 bilden hierbei in diesem vormontierten Zustand eine gemeinsame, unverlierbare, konisch ausgebildete Einschubeinheit, welche zur Montageerleichterung beim Einsetzen in nicht näher dargestellte Trägeröffnungen dient. Diese Trägeröffnungen, welche koaxial angeordnet sind, befinden sich beispielsweise in zwei miteinander zu verbindenden Teilen, insbesondere einem Karosserieteil eines Kraftfahrzeuges und einem an diesem zu befestigenden Lagerteil, beispielsweise einer Platte.For pre-assembly, the lower part 2 is inserted into the upper part 1 in accordance with FIG. 5, that the front region of the transition cone 30 of the lower part 2 is open the top of the counter detent 12 of the upper part 1 is located. Stands out in this position the flange 22 of the lower part 2 over the flange 10 by a certain amount the upper part 1 out. The conical end 36 of the lower part 2 and the centering slope 19 of the shaft 16 of the upper part 1 form pre-assembled in this Condition of a common, captive, conical insertion unit, which to facilitate assembly when inserting into not shown Carrier openings serves. These carrier openings, which are arranged coaxially, are, for example, in two parts to be connected, in particular a body part of a motor vehicle and one to it fastening bearing part, for example a plate.

Ist das so vormontierte Verbindungselement nach Fig. 5 in die entsprechenden, koaxial angeordneten Trägeröffnungen eingelagert, so wird von oben Druck auf den Abschlussflansch 22 des Unterteils ausgeübt, und zwar so lange, bis sich nach Fig. 6 der gesamte Abschlussflansch 22 in dem Flansch 10 des Oberteils 2 einlagert und mit diesem deckungsgleich ist. 5 in the corresponding, coaxially arranged carrier openings, so pressure is applied from above exerted the end flange 22 of the lower part until it is 6, the entire end flange 22 in the flange 10 of the upper part 2 stored and is congruent with this.

Der Abschlussflansch 22 kann alternativ mit mindestens einem unterseitigen Zahn 40 versehen sein, welcher auf die zentrische Innenverzahnung 11 des Flansches 10 des Oberteils 1 abgestellt ist.The end flange 22 can alternatively have at least one underside Tooth 40 may be provided, which on the central internal teeth 11 of the flange 10 of the upper part 1 is turned off.

Nach der Endmontage (Fig. 6) treten das konische Ende 36, das kreuzförmige Profil 33 und der Übergangskegel 30 über die Stirnseite des Schaftes 16 des Oberteils 1 heraus, wobei sich in dieser Position die Rastausnehmungen 24 des Unterteils 2 in den entsprechenden Gegenrasten 12 des Oberteils 1 einlagern. Wie aus Fig. 6 ersichtlich, sind hierbei die flexiblen Sektoren 17 des Schaftes 16 gespreizt und bewirken somit in und außerhalb der nicht näher dargestellten Trägeröffnungen eine funktionssichere Halterung des erfindungsgemäßen Verbindungselementes.After the final assembly (Fig. 6) occur the conical end 36, the cross-shaped Profile 33 and the transition cone 30 over the end face of the shaft 16 of the Top 1 out, the locking recesses 24 of the Store lower part 2 in the corresponding counter catches 12 of upper part 1. As can be seen from FIG. 6, here are the flexible sectors 17 of the shaft 16 spread and thus cause in and outside the carrier openings, not shown a functionally reliable holder of the connecting element according to the invention.

Zur Demontage wird ein Werkzeug, beispielsweise ein Schraubendreher, eine Münze usw. in die Eingriffsausnchmung 26 eingesetzt, um das Unterteil 2 in Drehung zu versetzen, beispielsweise entgegen dem Uhrzeigersinn. Diese Bewegung mit beispielsweise ¼ Umdrehung bringt die miteinander zusammenwirkenden Flächen der Gegenverzahnung 21 des Unterteils 2 und der zentrischen Innenverzahnung 11 des Oberteils 1 in Kontakt, was eine Rückbewegung in Längsrichtung des Unterteils 2 und das Austreten der Rastausnehmungen 24 des Unterteils 2 aus der Gegenrast 12 des Oberteils 1 bewirkt. Hieraus resultiert ein Zurückbewegen der flexiblen Sektoren 17 aus der in Fig. 6 dargestellten äußeren Lage in die Ursprungslage.A tool, for example a screwdriver, is used for disassembly Coin, etc. inserted into the engagement groove 26 to lower the bottom 2 in To offset rotation, for example counterclockwise. This movement with, for example, ¼ turn brings the interacting Surfaces of the counter toothing 21 of the lower part 2 and the central internal toothing 11 of the upper part 1 in contact, which is a return movement in the longitudinal direction of the lower part 2 and the emergence of the locking recesses 24 of the lower part 2 caused by the counter-locking 12 of the upper part 1. This results in a Moving the flexible sectors 17 back out of the outer one shown in FIG Position in the original position.

Nunmehr kann das gesamte Verbindungselement aus den Trägeröffnungen herausgezogen werden, indem auf den Flansch 10 bzw. auf den Flansch 22 ein Zug ausgeübt wird. Damit lässt sich beispielsweise das Unterteil 2 allein aus dem Oberteil 1 herausziehen oder das Oberteil 1 zusammen mit dem Unterteil 2 aus den Trägeröffnungen herausbewegen.The entire connecting element can now be pulled out of the carrier openings be by pulling on the flange 10 or on the flange 22 is exercised. This allows, for example, the lower part 2 from the Pull out the upper part 1 or the upper part 1 together with the lower part 2 move the carrier openings out.

Durch die erfindungsgemäße Gestaltung des Verbindungselements wird neben einer sehr funktionssicheren Halterung innerhalb von Trägeröffnungen auch eine gute Vormontage analog Fig. 5 mit unverlierbaren Teilen 1 und 2 sowie eine sehr gute Demontage bewirkt, welche auf einfache Weise durchzuführen ist, ohne dass hieraus eine Zerstörung des Verbindungselementes resultiert.The inventive design of the connecting element is next to a very reliable mounting within the carrier openings also one good pre-assembly analogous to Fig. 5 with captive parts 1 and 2 and a very good disassembly causes, which is easy to do without that this results in the destruction of the connecting element.
